Prepend section dates to individual entries in a summary log file
Searches for dates on lines by themselves. Uses that date to prepend all rows that contain SEARCHSTRING with the date, until it reaches another line with a date by itself. This fixed an issue with a specific log export where there would be a date, followed by all of the entries for that date.

see what's in your memory right now... sometimes you find passwords, account numbers and url's that were recently used. Anyone have a safe command to clear the memory without rebooting?

Lists unambigously names of all xml elements used in files in current directory
This set of commands was very convenient for me when I was preparing some xml files for typesetting a book. I wanted to check what styles I had to prepare but coudn't remember all tags that I used. This one saved me from error-prone browsing of all my files. It should be also useful if one tries to process xml files with xsl, when using own xml application.

Search and play youtube videos directly to terminal (no X needed)
Same as other command, however uses youtube-dl internal search (thanks to qoxxxx mentioning this) It does however seem to be a little buggy and youtube-dl crashes sometimes. ## pyt 'Stairway to heaven - Led Zeppelin' pyt 'brain damage - Pink Floyd' No web browser or even X needed. Just a cli and internet connection! mplayer is pauseable and can skip ahead This may break if youtube changes their search html.
